Django Rest框架，如何在 ModelSerializer 中包含 '__all__' 字段和相关字段

使用Django Rest框架开发Web应用程序时，ModelSerializer是一个非常有用的工具，它可以自动根据模型的字段生成序列化器。在ModelSerializer中，可以通过指定字段的方式来控制序列化器中包含的字段。如果想要在ModelSerializer中包含所有字段和相关字段，可以使用'__all__'参数。

python
from rest_framework import serializers
from .models import MyModel
class MyModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyModel
        fields = '__all__'

python
fields = ['name', 'age']

python
from django.db import models
class Person(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()
    address = models.CharField(max_length=200)

python
from rest_framework import serializers
from .models import Person
class PersonSerializer(serializers.ModelSerializer):
    class Meta:
        model = Person
        fields = '__all__'

python
from rest_framework.response import Response
from rest_framework.decorators import api_view
from .models import Person
from .serializers import PersonSerializer
@api_view(['GET'])
def get_person(request, pk):
    person = Person.objects.get(pk=pk)
    serializer = PersonSerializer(person)
    return Response(serializer.data)
